But Duell hoped that it would not be rushed. According to Duell, helping Starr, could eventually help Michael come to terms with his own loss. And by the summer of 2012, Michael and Starr have admitted their feelings for one another and began dating. However, their new friendship and budding romance is threatened with re-introduction of Michael's sister, Kristina (Lindsey Morgan) and the arrival of her reality show producer, Trey Mitchell (Erik Valdez).
